Title: Subcutaneous fat thickness measuring device
Inventor: KOBAYASHI TATSUYA
IPC: G01B17/02
Filed: 2001-11-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a high-performance subcutaneous fat thickness measuring device which improves accuracy in measuring a thickness of subcutaneous fat with a simple structure.  <P>SOLUTION: When a peak value of a reflected wave is received, masks are turned on.
